i took the time to find out the weights of my pro riders & advanced surfers that i make boards for, then went thru all the boards they were having the most success with & collected the volume data... i came up with a calculation of .35 litres volume per kilo of body weight. Eg: 100kg = 35litres. So grab your bathroom scales type in your weight on the calculator on the right hand side and times it by .35 = your answer! now you can test yourself and see what is the ideal volume for a PRO SURFER riding a high performance shortboard in everyday to good conditons is.
